medicine

At present, drug therapy is still an important method to treat atrial fibrillation. Drugs can restore and maintain sinus rhythm, control ventricular rate and prevent thromboembolism complications. 1.β blockers: the most effective, commonly used and often used alone drugs. 2. Calcium channel antagonists: Verapamil and diltiazem can also be effectively used to control the ventricular rate during atrial fibrillation, especially in exercise, and the effect of combination with digoxin is better than that of single use. Especially for patients without organic heart disease or normal left ventricular systolic function and with chronic obstructive pulmonary disease. 3. Digitalis: the first-line drug to control the ventricular rate of atrial fibrillation in an emergency. At present, it is mostly used to control the ventricular rate when left heart failure occurs in clinic. 4. Amiodarone: It can reduce the ventricular rate during atrial fibrillation and is not recommended for long-term ventricular rate control of chronic atrial fibrillation. Amiodarone and digitalis can only be preferred when other drugs are ineffective or contraindicated, and atrial fibrillation complicated with heart failure requires urgent control of ventricular rate. 5. Anticoagulant therapy: it is a necessary means to prevent thrombosis and embolism in patients with atrial fibrillation.

Surgical therapy

Labyrinth surgery: At present, it is mainly used for patients with atrial fibrillation who need heart surgery due to other heart diseases. The surgical effect is good, but the trauma is great.
